This invention relates to anticreepers or rail anchors, and has for one of its objects the provision of a device of this character that will be positive in action.

Another object of the invention is to produce a rail anchor which may be termed universal; that is a single size of the said anchor will accommodate any size rail.

A further object of the invention is to provide a rail anchor that will automatically tighten its grip upon a rail due to any creeping action thereof.

A still further object of theinvention is to provide a rail anchor,'comprising a lever adapted to engageone side of a rail base and passing thereunder alongside a railroad tie to the opposite side thereof, where the said lever is provided with a threaded portion having a nut threaded thereon and in engage ment with the web of the rail, so that any creeping tendency of the rail will cause the lever to partly rotate in the nut to further tighten the rail.

A yet further object of the invention is to provide a rail anchor of this character, that is'so formed, that when the nut is fully tightened, the forward edge of a flat side thereof will engage the upper or fillet surface of the rail base to prevent any rotary move ment of the said nut, and to cause the lever to be partly rotated by the tie, due to any creeping-action of the rail.

Another object is to produce a device of the character described in which the maxia practical embodiment thereof, but the in- 1930. I 'seri ai nb. 463,598;

Figure l is a fragmental perspective view-5 partly'i'n section ofa railroad track-embodyingapreferred form of'my invention. r Figure '2 is an 'end @section. of a rail with myimproved anchorapplied theretoand 1 Figure 3-. is a side view thereof looking from the right of Figure '2. a

' Referring to the :drawingsiin' detail 5 5 indicate-a pair of traclcrails suitably supported upon ties 6 one of whichis shown in thedrawings, 3 a pIn engagementrwiththe left side-of the rail base 7 is ahook portion 8 of alever9,

the bottom 10 of which passes underneath, therail j base 7*adjacent the tie 6 and then extends upwardly as at 11 and terminates in a downwardly sloping threaded portion 12, upon which. there is threadedly'mounted a nut 13 in abutment with the web portion 14 of the rail 5.

Both the lever and the nut are provided with a right hand thread and the nut is of such thickness that it will extend beyond the rail head 16, to permit the nut to be tight ened against the web by means of a track wrench. The abutting surface of the nut is chamfered so that the fillet 17 will not interfere withthe tightening of the nut. However, when fully tightened, the forward edge 18 of one of the flat faces of the nut will engage the upper surface of the base 7 to prevent any further rotation of the nut.

To properly apply the device, the trackened against the web 14 by unwinding same from the extension 12.

From the foregoing, it will be seen that when there is any tendency for the track to creep, the device being tight on the rail, the stationary tie 6 will cause the lever 9 to partly rotate in the-13 as shown in dot and dash 3 :fn'rther tighten therail against the tie and hold the said rail from v creeping.
